Covid and gatherings with 11 week old

Am I overreacting for not wanting to bring my baby to my husbands birthday event with his family? It will be a total of 12 people inside a house. It’s not a huge house so you can’t really social distance 6 feet. I don’t feel comfortable withSo many people because my little one gets over stimulated and I’m so afraid of Covid/flu season. My husband thinks I’m overreacting and says I can’t keep the baby inside forever. She goes to my parents but my parents rarely leave the house. My mom doesn’t leave at all due to her being high risk and my dad only leaves for importance like food, and he wears a mask. Do y’all think I’m over reacting? If it was a smallerCrowd I would be less anxious. I don’t want my husband thinking I’m keeping the baby away from his family but her health comes first.
